Ok so here's a little write up I did on my experience fiddling with them . Sorry it's copy pasted from another forum because I don't feel like tying it all out again . Lt might have to correct me on a few details though.
There not for every where , at least the full size versions. I'll have to find it but dale Billisley did a video where he said they where made by a guy for coon trapping to get around some of the laws regarding the fish steak set. Apparently it didnt count as visible bait if it was shoved in a pipe at the same height as a fish stick set. Then apparently LT got a hold of it and he was using them for coon before dp's. Around creeks ,ponds and even puddles and the like. And I have to say they are super fast . Heavy but it the ground is soft their stupid fast. Was playing with them for a bit and around ponds or the creeks around here and could have three or four sets in in about 3mins. Faster if I prebate them that being said this was really soft ground and I was usually able to just sink them in with one hand and no real effort. Slap the trap in the front and done. Never really had to get in the water either like with pockets. That being said though they are heavy. Was never walking more then 20yd from my truck or four wheeler so their not very good for anyone walking a huge line . Or if you have something like rocky bottoms or rip rap.
Anyway yeah apparently that how LT uses them and then he showed Clint and Clint being the kind a guy he is thought they could work for coyotes and the like and he started using them for multi species. Played around with this too ( and y'all know I don't catch anything but I'm dumb enough to play with this stuff so save your breath mkay ? Mkay thanks) I'll tell you driving in the 34"-24" o es in soft soil or wet clay, not real problem honestly prefer it to breaking in cable stakes. But of course baked red clay ...yeaahhh no. Then again I'd hope people would have the common sense not to use them in that environment.was thinking about driving some in when it was really wet and just using them as kinda. A semi permanent deal through the summer but never got around to it. HOWEVER. I did make what he calls minis and really all it is is that same pipe but on a 12" barn spike. Those where AMAZING with drags, usually just kicked in or split a grass clump and baited the mini nailed it in and re puffed the grass around it so you couldn't tell it was there. Wasn't there for eye appeal but did completely protect my bait and lure from the rain ( sorry really really really hate messing with flooded dirt holes) and since it was a few inches up off the ground in the clump I think the smell was spread better. Idk, though all I know my bait stayed good for a lot longer. Ants where LITTLE less of a pain too . Also pounding that spike in baked clay a whole 3-7" was wayyy easier then tryin to dig a dirt hole . Still a pain compared to just making a urine post on a stump or something but alot less than a dirt hole .
Remakes where easy. Would stuff some feathers in in one and just nail them under a bush or something with a trao in front . Coon seemed to like that along with the greys. Pain d some whit too like dps. Idk I likes then for what I did but y'all know me. I catch a few coon a fox or two and I'm happy. I have a crap load of trail cam footage of critters working them , somewhere , probably on a flash drive buried somewhere in my house idk. But yeah for a lazy hobby guy like me their nifty pro guys like y'all...nah. then again most of y'all can get away with urine, a trap , and stake so I guess when your at that level what most anything extra is kinda a waste ya know.
